A fast, simple and valued method is developed to observe the quality and quantity of different pharmaceutical brands of cefixime. A spectrophotometric method has been developed for analysis of cefixime (CFX) by reacting with 4-dimethylamino benzaldehyde (DAB) as derivatizing agent. The molar absorptivity of CFX-DAB, newly synthesized derivative was calculated as 3.2 x 105 L.mole-1cm-1 and λ maximum was 393 nm. The calibration curve was developed in range of 5-25 µg.mL-1as this concentration followed beers law. The derivatization reaction is stable and didn’t show any difference in absorbance with radiation interaction for up to one day. The percentage recovery of CFX was checked and calculated in different pharmaceuticals was within 95 to 99.5% with RSD value calculated in between RSD 0.69-0.96% (n=3), respectively. This newly developed and validated procedure was proved to be accurate and precise for the analysis of CFX. This method was successfully applied to check amount of CFX from 7 different brands of pharmaceutical preparations commercially available in Pakistan. |
